Application filed .Tune 10, 1925. Serial No. 36,075

. Be it known that I, ALBERT a citizen of the .United States, residing at the city and county of San Francisco and State of, California, have invented new and usefu' Improvements in Flying Machines, of which the following isa specification.

' This invention, relates to flying machines, andparticularly to improvements on the" driving and motor suspending mechanism shown in Patent No. 954,574, issued to Koeg'ler and Kamillo Stelzer, Jr., April 12, 1910.

The patent referred discloses a flying machine of the helicopter type in which steering was effected by shifting the center of gravity of the load carried with relation to the propellers. The machine however proved -.more or less impractical in experi-' mental tests asthe driving motor tended to rotate with the propellers.

-. The object: of the present invention-is togenerally improve and simplify the co'n-' struction and operation of flying machines tions One form which my invention may assume is exemplified in the following description.

and illustrated in the accompanying drawings, in which- 1g. 1 1s a s de elevation of the flying machine; Fig. 2 is a plan view of the gimbal rings from which the motor and carriage is suspended.

Fig. 3 is an enlarged vertical section of the gimbal rings 5 and 6 showing the manner of attaching the motor A to the inner gimbal ring and the bearing in which shafts 2 and 4 are journalled.

Referring to the drawings in .detail, and particularly Fig. 1, Aindicates a casing on which may be modeled a driving motor of suitable construction, B indicates the carriage in which passengers, 1oad,-etc., may be placed, and C and D the helicopters or propellers whereby the machine is lifted. The propellers are secured. to respective shafts as indicated at 2'and 4 and the are driven in op osite directions, and while any suitable orm of propeller me -be employed multi-main propellers ass own are pre'--, ferred. The mechanism whereby powerlisf transmitted-to rotate the'propellers and the I mechanism whereby the motor is suspended and secured against'rotation forms the subject matter of the present'application. It is perhaps best illustrated in-Figs. 2 and-3:.

A flying machine when in operation is of 'course. suspended from the propellersfand the carriage'B together with the motor A is suspended from a pair of; gimbal rings generallyindicated at .15 and6. These gimbal A. rings are connected asindicated at 7 and the i carriage B is suspended from the outer gimbal ring by'me'ans of downwardly extending arms 8. The motor A is suspended from the inner gimbal ring 5 and this is accomplished as follows: Mounted centrally onthe inner gimbal. ring is a bearing member consisting of two sections 8 and 9, these sections belng secured together by means of screws or the like as indicated at 10. Formed on theside of the bearing members 8 and 9 are arms'll,

and forming a pivotal connection between the arms and the inner gimbal ring are screws or other supporting means 12,'the members 7 arid 12 forming auniversal connection whereby movement of the motor may be obtained with relation to the carriage B and the propellers. Extending downwardly from the arms 11 is a pair of suspension arms 13 to which the motor A is secured. J ournaled in these suspension arms as at 14 are bevel gears 15, and intermeshlng with the bevel gears '15 are a second [pair of bevel gears indicated at 16 and 17. shaft extends through the gears 16 and 17 as indicated at 4'and this shaft is directly con nected with the motor and is driven thereby. The gear 16 iSsecured-on' the shaft and it transmits power through the gear 15 to rotate gear 17 in the direction opposite to-the gear 16 and shaft 4. The gear 17 is secured on the sleeve shaft 2 and as this shaft carries the propellers C and the shaft 4 the propel-'v prevented b the opposed -rotation of. the

propellers. he thrust of the propellers will p thus be in a downward direction and the carriage together with the motor will accordingly be lifted.

If it is desired to steer the machine in any direction it is accomplished as described in the patent already referred to by shifting the center of. gravity of the load with relation to the motor and the propellers. This load can be moved in any direction due to the universal connection formed between the carriage, the motor, and the propellers, and flight in any direction can be obtained. The load when shifted is secured by a suspended chain 20 and an attaching hook 21;. The onl novel feature in the present application w en comparison is made with the previous patent referred to is the transmission consisting of the gears 16, 1515, and 17; the anti-friction bearing supporting the same; and the suspending arms 13, whereby the motor is supported and secured against rotation. No particular stress is, therefore, laid on the steering mechanism just described.

Having thus described my invention, what I claim and desire to secure by Letter Patent is 1. In a flying machine of the character described, an inner and an outer gimbal ring, a bearingmember pivotally supported in the inner ring, an inner drivin shaft and an exterior driving sleeve sha t journaled in said bearing -member, a driving motor suspended from the bearing and secured against rotation with relation thereto, means for transmitting power from the motor to rotate the inner shaft and the sleeve shaft in opposite directions, and a propeller on each shaft.

2. In a flying machine of the character described, an inner and an outergimbal ring, a bearing member pivotally supported in the inner ring, an inner drivin shaft and an exterior driving sleeve sha t journalled in said bearing member, a driving motor suspended from the bearing and secured against rotation with relation thereto, a direct connection between the inner driving shaft and the motor, a bevel gear secured on said shaft, a bevel gear secured on the driving sleeveshaft, interme'diatebevel gears intermeshing with said gears and transmitting power from the motor to the'sleeve shaft in an opposite direction, and a propeller on each shaft.

3. In a flying machine of the character described, an inner and an outer I gimbal ring, a bearingmember pivotally supported in the inner ring, an inner drivin shaft and an exterior driving sleeve shaft journalled. in said bearing member, a driving motor suspended from the bearing and secured against rotation with relation thereto, a direct connection between the inner driving shaft and the motor, a bevel gear secured on said shaft, a bevel gear secured on the driving sleeve shaft, intermediate bevel gears intermeshing with said gears and transmitting power from the motor-1'0 the sleeve shaft in an opposite direction,v

a propeller on each shaft, a piyaetal vconnection between the inner gimbal ring and the outer gimbal'ring, and a lendsupporting carriage suspended from the outer gimbal ring.

4. In a flying machine of the character described, an inner and an outer gimbal ring, a. bearing member pivotally supported in the inner ring, an inner driving shaft and an exterior driving sleeve shaft journalledin at said bearing member, a drivingmotor suspended from the bearing and secured against rotation with relation thereto, a direct connection between theinner driving shaft and means in the bearing member.
